What is a Tube type continuous annealing furnace? Introduction to the advantages and characteristics of the forging furnace

Tube type continuous annealing furnaceIt is a kind of heating equipment using natural gas as fuel, which is mainly used to heat metal materials to the required forging temperature in a short time.，Heat of combustion based on fuel. Natural gas is sprayed from the burner, mixed with combustion-supporting air and burned to produce high-temperature flame and smoke. These high-temperature flames and smoke transfer heat to the metal materials in the furnace by radiation and convection, so that they gradually heat up to the temperature required for forging.，is developed and improved by One-combustion energy saving。

1、Brief introduction of Tube type continuous annealing furnace

Tube type continuous annealing furnaceIt is a kind of equipment which uses gas as fuel and is specially used for heating metal before forging.。

2、Structural advantages of Tube type continuous annealing furnace

The Tube type continuous annealing furnace has the following structure

1. combustor

The device that mixes natural gas with combustion-supporting air and ejects it is the core component of the heating furnace.

2. Radiation chamber

The heat load of the main place for Tube type continuous annealing furnace heat exchange accounts for about 70%-80% of the whole furnace. The furnace tube in the radiation room conducts heat through flame or high-temperature flue gas, which is mainly radiant heat, so it is called radiation tube.

3. ventilation system

Ensure the gas flow in the furnace and maintain the stability of the atmosphere and temperature in the furnace.

4. Waste heat recovery system

Used to recover the exhaust heat of the heating furnace. There are two kinds of recovery methods, one is to recover by preheating combustion air, so that the recovered heat can return to the furnace again; The other is to use another recovery system to recover heat. The former is called air preheating mode, and the latter is usually called waste heat boiler mode.

5. furnace chamber

A space for holding metallic materials for heating.

4、Working principle of Tube type continuous annealing furnace

Tube type continuous annealing furnacein the course of work,The high-temperature flame and flue gas generated when the fuel burns in the furnace are used as heat sources to heat the medium flowing in the tube to reach the specified process temperature. Fuel is ejected from the burner and burned, resulting in high-temperature flame and high-temperature flue gas. The high-temperature flame transfers heat to the furnace tube in the radiation chamber through radiation, and then to the medium in the furnace tube. The high-temperature flue gas enters the convection chamber of the heating furnace upward due to the suction force of the chimney or the action of the induced draft fan, and the heat is transferred to the furnace tube in the convection chamber by convection, and then to the medium in the furnace tube.，The structure is novel, special, advanced, reasonable and scientific.，it is usually composed of furnace chamber, ventilation system, ventilation system, recovery of waste heat and furnace chamber，it has the functions of quench, hardening and tempering, Forging heating, normalizing and anneal，multifunctional, with functions such as Casting heating, heat treatment, temper, quench and Casting heating，be of high quality，The price is low and affordable。
